LIGHTING ATTACHMENT FOR GAS-STOVES.

SPECIFIGATION forming part of Letters Patent N 0. 741,991, dated October20, 1903. Application filed February 3, 1903. Serial 1T0. 141.673- (Nomodel.)

To aZZ whom it may concern.-

Be it known that I, LESLIE E. ADAMS, a citizen of the United States, anda resident of Galena, in the county of'Delaware and State of Ohio, havemade certain new and useful Improvements in Lighting Attachments forGas-Stoves, of which the following is a specification.

This invention relates to lighting-attachments'for gasstoves; anditconsists of a new and improved attachment of that character having apilot-light adapted to be kept burning with gas stored under pressure ina suitable holder or tank.

It is well known that the pressure of gas varies in the mains and thatat times is so low as not to furnish sufficient gas to keep a lightedstove burning. At times it becomes necessary to leave the room or housefor a short period of time, in which there isa lighted gas-stove. Duringthis period the pressure of gas in the mains may fluctuate and get solow as to allow the jets to flicker outor be blownoutbyslightdraftofair.Myinvention is designed for relighting the jets upon return flow of gasto normal pressure in the mains, and I effect the relighting by peculiarmeans which I will describe as follows with reference to theaccompanying drawing, forming a part of this specification, and in whichis shown a front elevation of my invention in use.

While my improved attachment is adapted for lighting any type ofgas-stove, in the drawing I show it in connection with an ordinaryheating-stove A. The pipe B shown is the usual gas-supply pipe whichordinarily enters the stove with a horizontal portion 0, having acut-off D at the stove end thereofl Eindicatesa suitable holder intowhich gas is forced, as will be described further on.

F indicates a small tube,having in its length a regulating-valve G. Thetube F is intended for conveying gas from the tank E to the pilot-lightH, as shown. In connection with the tank E, I employ a pressure-gage I,the use of which will be understood. In my drawing I show the tank Esecured to the pipe 0 by two clamps J; but obviously any other means maybe employed therefor which is adapted to the purpose.

K indicates an ordinary air-forcing pump,

shown resting on the floor. Near the lower end of this pump I provideinlet and outlet nipples L M,having check-valves O P, the lattercheckvalve P being adapted to be seated by pressure of air in thepump-cylinderon the downstroke of its piston, and the former O isadapted to be opened by the same pressure. In other words, as will beunderstood from the following description, upon upward stroke of thepump piston suction produced in the pump-cylinder will unseat the valveP and draw in gas through the nipple M. Downward stroke of thepump-piston puts the gas in the pump-cylinder under pressure adapted toseat the valve B and open the valve 0. The nipple L and a suitablenipple Q on the tank E are connected, preferably, by flexible tubing R.The nipple Q should have a cut-0E valve S, as shown. At any suitablelocation on the pipes B or C, I provide a nipple T, having a cut-offvalve U, and I connect the latter nipple 'l with the nipple M on thepump preferably by flexible tubing V.

In describing the use of my invention it becomes necessary only to saythat shoulda person desire to leave a lighted gas-stove for a short timethe valves S and U'are opened and the pump worked, as will beunderstood. Upon upward stroke of the pump-piston gas is drawn in thepump-cylinder through the tube V, and upon downward stroke of thepump-piston the pressure of gas produced thereby in the pump-cylinderlifts the valve 0 at the pump end of the tube It and gas is forcedthrough the said tube E into the tank E. The pump should be worked untilsufficient gas is stored in the tank E adapted for keeping thepilot-light burning while the person is absent from the room. Nowobviously with my improved lighting attachment a person can fill thetank to the desired pressure and with the pilot-light lighted leave thegas-stove burning and feel assured that should the jets go out, owing toinsufficient supply of gas or from other causes, upon renewed pressureor supply of gas the jets of the stove will be regulated by thepilot-light.

Having thus described my invention, what I claim as new, and desire tosecure by Letter Patent, is

1. An improved lighting attachment for gas-stoves, employing a tank, apilot-light as too specified, tubing connecting the said tank saidnipples, the tank and the gas-supply main, and valves at the feed andsupply ends of the said tubing, adapted one to close the inlet into thetank, and the other for cutting 15 off the supply at the gas-mainsubstantially as described.
